Baleen whales swim through the water with their mouth open, taking in large volumes of water that contain the tiny ocean creatures. The fringed baleen then acts as a sieve â the whales squeeze the water out through the baleen, leaving their food caught on the baleen. Then they use their tongue to wipe the baleen clean before swallowing their food. In the northeast U.S., the common toothed whales are pilot whales, dolphins, and porpoises. Common baleen whales are humpbacks, minkes, and right whales.
